Building sand is appreciated by the architectural projects, consisting of manufactured crushed stone and organic sand. The artificial crushed stone is produced by crushing unprocessed trash conducted by crushers and sand manufacturers. There are three reasons for manufactured sand getting the model of building yellow sand that is recommended by the state. The first is to prevent the devastation of riverbed caused by excavation of water sand, therefore preventing the floods and security dangers. The second is to lower the energy usage and build price advantage. The exploration of lake sand needs to salvage, take away sludge, dry and other backlinks. The unnatural sand is definitely some of bashing and screening links.
Because of the large scale of artificial yellow sand making machine, the electric power consumption of per load of yellow sand is relatively lower than river fine sand. Besides, the river fine sand resource is lower than the rock and roll resource, which usually needs reduced resource taxes, thus resulting in the price advantage of artificial sand compared with lake sand. The 3rd is the hard rock products that manufactured sand uses perfectly meeting the requirements of high-strength cement. The current yellow sand making machine can totally meet the grading requirements of artificial sand, which makes the performance for artificial fine sand better than the river fine sand.
The advocation of produced sand is usually inevitable. But , the produced sand requires a large number of unprocessed trash. Although there will be large amounts of rock methods, however , they can not be over exploited; in any other case, it will trigger excessive damage of the environmental environment. Some areas have previously appeared the depleted condition of sand dirt, especially in the east provinces that earliest develop the yellow sand and gravel industry. Therefore , how to solve these complications?
Actually, we certainly have lots of squander resources to make use of, including building wastes, hudproblem, blast furnace slag, enveloppe and so on. Whenever we can use these wastes to manufacture yellow sand, it will tremendously ease the shortage issue of crushed stone...
